2014 Map of Union Pass

About this map

The Black Mountains dominate this 2014 survey of the high desert terrain east of the Colorado River. This area is defined by its historic transportation corridors and topographic landmarks, most notably the strategic gap at Union Pass. Modern infrastructure, represented by Az 68, cuts through the landscape alongside remnants of earlier routes like the Old Kingman Hwy. The presence of Katherine Mine Rd in the northwest corner points to the region's mining heritage, while natural water sources like Secret Pass Spring emphasize the importance of hydration points in the arid Mojave Desert. The map reveals a high-relief landscape where prominent peaks such as Sugarloaf Mtn and Thumb Butte served as navigational beacons for travelers moving between the river valley and the interior plateau.
